Completely rework Lighthouse Medbay (#1988)

* Completely rework Lighthouse Medbay

* Fixgridatmos the Lighthouse, also fix APC wires

* Touch up the piping and cryo, surgery, yellow area. Microwave!

* Add posters, decal lines, signs and chem fuel dispenser

* Remove some firedoors, fix reception ones, add droppers to chem

* Fix Lighthouse med feedback for morgue, hallway lights, jani button, reception firelocks

The ICU light shall stay on the dark area because oh god the contrast dies otherwise. Same with airlocks there too. The contrast is purely accidental but damn it turns out to be very tricky to have and keep.

* Change reception back to previous WIP

* Remove a light as per feedback, add table to morgue, windoor & APC names

* Hopefully last fix - defib from cryo now faces ICU, move trash spawn around
